The Power of Stem Cells

The video discusses the significance of stem cells in renewing tissues and organs in multicellular organisms. It highlights the use of adult stem cells from sources like umbilical cord and bone marrow in medical therapies, such as regenerating heart tissue. The potential of embryonic stem cells to regenerate spinal cords or build new limbs is explored, along with the ethical concerns raised by religious groups, particularly the Catholic Church, due to their potential to develop into a complete human.

What is the primary role of stem cells in multicellular organisms?

• To fight infections

• To renew tissues and organs

• To produce hormones

• To generate energy

How are adult stem cells used in medical therapies?

• They are used to create vaccines

• They are injected to regenerate damaged tissues

• They are used to enhance memory

• They are used to improve digestion

What is a significant benefit of using a patient's own stem cells for therapy?

• They are cheaper to produce

• They are easier to harvest

• They reduce the risk of rejection

• They work faster than other cells

What potential medical advancements are scientists hoping to achieve with embryonic stem cells?

• Enhancing athletic performance

• Improving eyesight

• Regenerating spinal cords and building new limbs

• Curing common colds

Why are some religious groups opposed to embryonic stem cell research?

• Because it is not effective

• Because the cells have the potential to become a human

• Because it involves animal testing

• Because it is too expensive
